Need help...Stevie Wonder song? (hey, not a war thread!)

Anyone here a Stevie Wonder fan? I'm trying to track down this song (have been for while now).

I'm about 90% sure it's Stevie Wonder because a) I thought I heard someone actually say it one time and b) it sounds like something from that whole "Superstition" era. It's VERY funky.

It's an instrumental (at least all that heard of it), so with no lyrics to quote, this might get tough. But some of you into music and instruments might be able to nail it down.

It's mid-tempo, real heavy on the 1 beat. There's a real prominent clavinet (is that what that instrument is called? It's a real cool "honky/quacky" sounding keyboard thing...it's the instrument that plays that main lick/hook in "Superstition"...you know if it if you hear it).

This song just seems to repeat a simple progression over and over again. I don't know the chord symbol number thing, but if the song was in, say, E it would go from E to D to A (kind of a descending/reverse I-IV-V progression).

I'm f***ed, ain't I?

Sadly, I have nothing else but that to go on.

I asked a question like this a year or so ago (a Smiths song) and many of you nailed it right away.

I just burned through amazon.com/cdnow.com and clicked on every available sound clip they had (whew!).

No luck.

I mean, there's a TINY chance it's not even him, but I'd put money on it. I heard it back last summer as bumper music on Rush or somebody and I think he even said "...Mr. Stevie Wonder playing us back in..." or something. Then I heard it on a movie. Not "Dazed and Confused", but something like that (set back in the 70's).

Then, just yesterday out of the blue, I was listening to some syndicated sportstalk radio show late at night and they had it playing and it all came back to me and I remembered how cool it was.

So, I THINK it's Wonder, but sadly all the songs on his albums at amazon/cdnow aren't available for listening samples. Just the first five or so.

This would SO much easier if it had lyrics, I know. I mean, it doesn't help anyone for me just to go "beyowng...chick-a-bow-dow...beyown-chank-a-a..."

if you've google'd for "stevie wonder instrumental" for no joy, and similar acquisition search nets nothing suitable, we might need to widen the search to "stevie songs with long funky instrumental sections suitable for looping"

... suddenly these jump to mind as candidates for radio airplay

higher ground (red hot chili peppers version not as good as Basso Mix)

i wish (also subject to almost as many cover versions as superstition)

living for the city (extended version over 7 minutes... lots of instrumental bars)

you might have to search the soundtrack listings of all last years retro movies for prompting
